MIXING-MACHINE.

Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed October 28, 1909. Serial No. 525,081.

To all whom it may concern:

Be it known that I, FREDERICK T. :ARNOLD, a citizen of the UnitedStates, residing at Fort Robinson, in the county of Dawes and State ofNebraska, have invented certain new and useful Improvements in Mixing-Machines; and I do hereby declare the following to be a full, clear,and'exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in mixing machinesand more particularly to that class adapted to be used for mixingplastic materials, such as con crete, mortar, plaster, etc., for allclasses of construction and my object is to provide means for gearingthe receptacle to one of its supporting wheels whereby when the wheel isrotated, the receptacle will-be likewise rotated and a further object isto provide suitable means for operating the gearing mechanism, wherebythe receptacle will be attached to or disconnectedfrom the wheel.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claims.

In the accompanying drawings forming part of this application, Figure 1is a front elevation of the mixing device complete. Fig. 2 is a verticalcentral sectional view therethrough. Fig. 3 is an end elevation of thedevice. Fig. 4 is a similar view of the .op-

posite end of the device. Fig. 5 is a detail plan view of the mechanismemployed for securing the closure in its closed position. Fig. 6 is adetail sectional View thereof, and, Fig. 7 is a detail sectional viewthrough the hinged end of the closure.

Referring to the drawings in which similar numerals designatecorresponding parts throughout the several views, 1 indicates thereceptacle or body which is in form a modified regular octahedron ingeneral outline substantially as shown on drawing and through the centerof the body is disposed an axle 2, said axle being of sufficient lengthto roject beyond the walls of the body.

Sue Wall of the receptacle through which the axle extends, is providedwith a flanged collar 3, which forms a bearing for that end of the axle,while the opposite end of the axle extends through the hub 4 of a bevelgear 5, said gear being attached to the outer face of the end wallof thebody by means of rivets or the like 6 and the flanged collar 3 islikewise attached to its respective end of the body by means of rivets 7and in order to securely brace the end wall through which the collar 3extends, a spider 8 is introduced overthe bearing portion of the collar3 and securely attached to the outer face of the end wall.

The receptacle 1 is securely held in position on the axle and preventedfrom moving longitudinally thereon by providing a circumferentialgrooove 9 in that portion of the axle 2 extending through the collar 3and into said groove is introduced the end of a pin 10 carried by thecollar 3, this construction permitting the receptacle to rotateindependently of the axle, but holding the same against longitudinalmovement thereon.

The ends of the axle 2 have mounted thereon supporting wheels 11 and 12,the wheel 12 being retained in position on the axle by providing awasher 13 which is introduced over the end of the axle and bears ag ainst the outer end of the hub of said wheel 12, a pin 14 being extendedthrough the axle to retain the washer in position, while the inner endof the hub is engaged by a collar 15, which collar is fixed in anysuitable manner-to the axle. The wheel 11 is caused to rotate with theaxle 2 by providing a. key 16, said key entering a. seat. 17 in the axleand having a projetcion 18 thereon, which enters a seat 19 in the hub ofthe wheel 11, whereby when said wheel is rotated, the axle will likewisebe rotated.

The key 16 is of considerable length and hasattached to its inner end abevel gear 20, which is adapted to be moved into engagement and meshwith the gear 5, whereby the receptacle 1 will be rotated and as the key16 is slidably mounted in the seat 17, said gear 20 may be moved into orout of engagementwith the gear 5 thereby. The outerend of the key 16 isprovided with an upwardly extending tongue 21, which enters a spiralchannel 22 on the interior of a. cam 23, saidcam. hax'ing a bore 24.extending inwardly from one end thereof, into which the end of the axle2 is extended and said cam is rotatably mounted upon the end of the axleand held in position thereon by means of a screw 25, which screw extendsthrough the closed end of the cam and enters the end of the axle and inview of the spiral trend of the channel 22, it will be readily seen thatwhen the cam is rotated on the end of the axle, said key will be movedinwardly oroutwardly, thereby engaging or disengaging the bevel gearsand it'will likewise be seen that by placing the cam adjacent the outerend of the hub of the wheel 11,. said cam will serve to prevent thewheel from leaving the axle. In order to readily operate the cam trotate the same on the axle and move the gear 20 into engagement withthe gear 5, a lever 26 is attached to the outer face of the cam 23, sothat by grasping the lever and swinging the same in the arc of a eucle,the cam will be likewise rotated, the lever and cam being held in afixed position when desired by providing 'alatch 27, the lower end ofwhich-engages either one of a series of notches 28 in the periphery ofthe hub of the wheel 11, the latch 27 being operated through the mediumof a spring pressed lever 29 adjacent the upper end of I the lever. 26.

the shaft 2, said collars being positioned between the wheels and theends" of the receptacle 1 and to these collars are attached a frame orhandle 31, whereby the vehicle or mixer may be propelled, but instead ofusing the frame, a pair of shafts (not shown) may be substitutedtherefor and the vehicle propelled by horsepower.

Attached to the end of the receptacle and extending over the gears 5and'20- is a two-part shield 32, which is adapted to preventforeignparticles from coming in direct contact with the gears and inorder to further protect the bearing-parts of the device, each of thecollars 30 is provided with a band 33, which extends a distance beyondeach end of the collar and prevents the gravel, etc., from enteringbetween the ends of the collar and parts adjacent thereto, the bandsbeing fixed to the collar inany suitable manner.

The meeting edges of the several walls of the receptacle 1 are securedtogether and rendered water tight by lacing'over said meeting ed essuitable angle irons 34, which are secure in position over the edges bymeans of rivets 35 or otherwise, and in order 'to gain access to theinterior of the receptacle, one of said walls is left free to form adoor 36, one edge of which is at tached to the receptacle by means ofhinges 37, while the remaining ed es are secured in position by means ofsuita le locks which comprise latches 38, which'are pivotallysecured'around the edges of the door section 36, said latches havinghandles 39 thereon, whereby the latches may be readily. swung on theirpivot bolts 40.

The free end of the latch 38 when swung into locked position extendsover the edge ceptacle will be securely clamped together when thelatchis introduced to itsfull extent into the notch.

To form a water tight seal between the edges of the door and the wallsof the receptacle, strips of rubber or the like 44 and 45 are secured,respectively, to the edges of the receptacle 1 and door 36, the rubber44 extending slightly beyond the edges of the walls of the receptacle 1and contact with the rubber 45, around the edges of the door 36, so thatwhen the latch is operated to lock the door in its closed position, therubbers will be securely clamped together.

As before stated, this device is normally operated by pushing the entiredevice forwardly or rearwardly to thoroughly mix the contents of thereceptacle, but if preferred, the gear 20 may be disengaged with thegear 5 aITdthe receptacle 1 rotated around the axle manually through themedium of handholds 46 which are placed at suitable intervals on thefaces of the receptacle and these hand-holds may be also employed forturning the receptacle to such position as to discharge the contentsthereof when the door 36 is opened and when the gear 30 is in mesh wlththegear 5, the receptacle 1 may be rotated by turning the device in acircle, employing the wheel 12 as a pivot, the travel of the wheel 11causing the receptacle 1 to rotate.

In operation, the lime, cement, sand and other products employed informin the concrete or other plastic material are p aced at somedistance from the construction for which the concrete is used and aftera pro er quantity of the various ingredients, toget er with the properamount of water are placed in the receptacle, the door is securely fas-'tened; The lever 26 is then rotated to move the-key 16 lengthwise andforce the ear 20 tion and the same operation again performed. 7

By providing a device of this class, it will be readily seen that thearduous labor of mixing the ingredients with shovels, hoes or the likeand requiring a number of men to perform the operation, will be entirelydispensed with and further in view of the small cost of the mixer, thesame may be ably used on small jobs. It will further be seen that inviewof the shape of the receptacle and the manner of mounting the same onthe axle, the contents thereof will be thoroughly mixed when thereceptacle is rotated as described and in'view of the lightness of themixer,-it can be readily operated 'by one or two men and it will furtherbe seen that as substantially all the parts of the device areconstructed of metal, it will be practically indestructible from use.

What I claim is:

1. A mixing device, comprising the combination with a receptacle, of anaxle extending through receptacle, supporting wheels for said axle, akey adapted to one of said wheels with the axle, a gear fixed to saidreceptacle, a similar gear fixed to one end of said key and means tomove said key longitudinally, whereby .the gear on the key will be movedinto or out of mesh with the'gear on the receptacle.
